Distribute prebuilt bootstraps for common hosts

* am/bootstrap.am: New file, factored out of bootstrap/Makefile.am.
* bootstrap/Makefile.am: Use bootstrap.am.

* prebuilt/Makefile.am:
* prebuilt/i686-pc-linux-gnu/Makefile.am:
* prebuilt/mips-unknown-linux-gnu/Makefile.am:
* prebuilt/x86_64-unknown-linux-gnu/Makefile.am: New files.

* configure.ac: Output the prebuilt/ makefiles.
* Makefile.am: Descend into prebuilt/ when making dist.

* meta/uninstalled-env.in: Arrange to put prebuilt/ in the beginning of
  the GUILE_LOAD_COMPILED_PATH.  Also fix a case where bootstrap/ wasn't
  being correctly added to the load path.
